What is the use of computers in astronomy?

Answer 1

Space exploration requires complex calculations using many variables. These apply to astronomical information for planets, moons, and other bodies, as well as the precise accelerations and trajectories for spacecraft and probes. On Earth, travel on the surface or in the air can be controlled effectively by human coordination and relatively simple vehicles. In space, small errors or miscalculations can create serious problems that cannot be easily corrected. Computers provide faster and more flexible handling of data, both in planning a mission and in analyzing parameters during a mission. Without them, effective space exploration would be nearly impossible.

Answer 2

By viewing, photographing, and analyzing astronomical phenomena, scientists can deduce characteristics of the bodies. Astronomy can be conducted using visible light, but also with other radiation frequencies such as infrared, ultraviolet, x-rays, and gamma rays.

There are innumerable ground-based telescopes, both professional and amateur. Orbital telescopes include the Hubbell Space Telescope (visible light), Spitzer Infrared Telescope, and the Chandra X-Ray Telescope.

Answer 3

Computers can offer great help to astronomy. There is an important branch of astronomy called "astrophysics" which deals with, but not limited to, movements and interactions between celestial bodies. To study the behaviour of these complex systems math and computer are essential tools. Good mathematical models and powerful computers can help predict the evolution of stars, planets, galaxies, etc.
